Improvement in base-pieces of locomotive smoke-stacks

IMPROVEMENT IN BASE-PIECES OF LOCOMOTIVE SMOKE-STACKS.

To all whom it may concern:

Be it known that I, PETER S. EBBERT, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Saddles or Base-Pieces for Locomotive Stacks or Chimneys; andIdohereby declare the following to be a full, clear, and exact description'of the same, reference being had to the accompanying drawings, making apart thereof, in which- Figure 1 represents an elevation of the saddleor base-piece in question with hot-water pipes arranged therein. Fig. 2represents a central vertical section taken through Fig. l; and Fig. 3represents a horizontal transverse section through the pipes, showingthe top plan of the saddle or base-piece.

Similar letters where they occur in the several figures denote likeparts in all.

In heating the water that is to supply the boilers of locomotives by aseries of' water pipes or spaces arranged in the stack or chimneythereof, there must be, of course, considerable condensation on theoutside of said pipes orwater-spaces. This condensed vapor, if allowedto run down into the stack, will eventually dampen the heat or fire andotherwise injure the boiler; if allowed to iow or run over the outsideof the boiler, will corrode and soil the engine.

The object of my invention is to so construct the saddle orbase-piecewhich receives the hotwaterapparatus and outer shell of the stack asthat it shall collect all the water which forms in the interior of thestack by the exhaust-steam coming in contact with the pipes and conveyit away without allowing it to injure or damage the engine or corrodeany of the parts of the stack.

To enable others skilled in the art to make and use my invention, I willproceed to describe the construction and operation thereof withreference .to the drawings.

Th'e saddle maybe cast in one single piece, and its general form maybeseen in the drawings. It consists, mainly, of a cylindrical center part,A, which is convex at its lower part,

said lower part having' upon 1t' a similarly- .shaped flange, B. Theeonvexity of the lower part of the saddle should be such as to neatly tover the top of the boiler to which it is to be bolted. The upper end ofthe centerpart, A, is square, or nearly so, and has upon it, first, ahorizontal flange, C, and then a small vertical flange, d, rising fromthe outside of the horizontal flange C.

A neck, D, is formed -in the inside of the saddle, through the center ofwhich is an opening, E, for the heated products of combustion and theexhauststeam to pass through. That portion of the neck D which isnearest the opening E is turned upward, as seen at c, so as to formbetween it and the wall of the center part, A, a trough or recess, e,into which the condensed steam drips from the hot-water pipes F, placedaround said neck. From this trough or recess e should lead a water-pipe,G, for conveying olf and discharging in any convenient way or place thewater which accumulates therein.

Ribs i t' may be cast on the outside of the saddle, extending from thetop to the bottom flanges, so that the saddle may be light and strong.The base of the outside shell of the stack rests on the horizontalfiange'C and against the outside vertical flange, a, to which it may bebolted or riveted in any of the usual Well-known ways. The drawingsrepresent the saddle as arranged for the reception of a series of pipessuch as recently patented by me; but it may be differently arranged fordifferent water-spaces without departing from the general constructionthereof.

Having thus fully described the nature of my invention,\vl1at I claimtherein as new, and desire to secure by Letters Patent, in theconstruction of saddles or base-pieces for the stacks or chimneys oflocomotives in which the feed-water for the boilers is heated, is-

The trough or receiver le for catching the wafer or condensed steam thatdrips from the pipes, and the waste-pipe for conveying it away,substantially as described.
